RUFFLER COMPANY, OF SAME PLACE.

InorFLine ATTACHMNT `Fon SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 272,427, dated February 2O, 1883.

` Application filed October 3, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES GROTZ, a citizen ofthe United States, residing at Oskaloosa, in the county ot' Mahaska and State ofIowa, have invented a new and useful Ruftling and Shirring Attachment for Sewing-Machines, ot' which the following is a specification, reference being had to the accompanying drawings.

This invention relates to rufding and shirring attac ents for sewing-machines; and it consists in certain improved mechanism for adjusting1 thel rufliing-blade carrier and the operating'plate or lever in relation to each ot.l1er,for the purpose of regulating the fullness ofthe gathers.

Ihavein the drawings hereto annexed shown my improvements applied to the rufdng and shirring device for which Letters Patent of the United States were issued to Thomas B. Garretson on August 29,1882, No. 263,332; but l lwould have it understood at the outset 4that my improvements may, by making lSuch modifications as will readily suggest themselves to 'those skilled in the art to which -it appertains, be applied to ruftling and shirring devices of other kinds and patterns'fwithout departing from the spirit of my invention.

In the drawings, Figure l' is a perspective view of a ruftling and shirring attachment having my improvement. Fig.-2 is a side'view, the cap plate or disk having been removed. Fig. 8 is a perspective View of the adjustingdisk detached. Fig. 4 is a detail view of the operating plate or lever. Fig. 5 is a detail view of the raiding-blade and carrierprevious to being joined together, and Fig. 6 is 'a sectional View taken vertically through the same after being connected.

Corresponding parts in the several figures are denoted by like 'letters of reference.

In the drawings, A represents the presserfoot, forming part of the rnftling device, and adapted to be attached to the presser-bar of a sewing-machine. Said presser-foot has at its front end an arm, B, to thesde of which the carrier C is pivoted. A spring is employed to force the carrier C in a rearward direction; but in the construction and arrangement of this mechanism no novelty is here claimed.

APivoted upon the same fulcrum as the carrier'C is the operating plate or lever D, which has a segmental slot, E, through which extends a stud, F, projecting laterally-from the carrier C. Lever D has a laterally-projecting stud, G, at the rear end of slot E. 4

H is the adjusting-disk, which is pivoted upon the stud F, closely adjoining the lever D.

YSaid disk has an eccentric slot, I,.thr.oug'h which extends the stud G of lever D, and said disk is provided with a crank or handle, J, by means of which it may be readily turned upon its pivot orjournal.

K is the cap plate or disk, which is pivoted upon the `end of stud F, adjoining disk H, and provided with au opening, L, through which the handle Jot said disk extends. This cap-plate turns with the disk H, which it covers and protects. vIt may also be graduated, as shown, in order to indicate the relative position of the carrier and lever.

The operation will be readily understood. The carrier is in this case operated by the needle-bar of the machine striking the beveled rear end of the lever D. Hence by adjusting A said lever D so that it will be struck by the needle-barearlier or laterin its downward movement, as may be desired, the required length of stroke may be imparted to the ruiiiing-blade, and the fullness ot' the gathers or ruffles thus be regulated. To adjust the lever D it is only necessary to turn the disk H by means ofhandie J. The eccentric slot I will then guide the stud G of lever D in such a manner as to raise or lower said lever, as required.

The carrier is provided'at its lower end with a C-shaped clamp, M, to receive the rufdingblade N, which is constructed, in the usual manner, of steel, and provided at its inner end with perforations O. Said inner end is inserted into the clamp M, whichis then compressed forcibly, thereby forcing part of the metal of which it is composed into the openings O, and thus holding the blade securely. In this manner I dispense with the use ot' rivets and attach the ruffling-blade in a cheap and exceedin gly durable manner. This method of connecting the rufling-blade with the carrier is not herein claimed but I reserve the privilege of making it the subject ot' a future application for Letters Patent.

I claim and desire to secure by Letters Patent of the United States- IOO I. In a rufiing and shirring attachment for sewing-machines, the combination of the ruf-4 iiing-blade carrier, the operating-lever pivoted upon the same fulorum as said carrier, and provided with a. laterally-projecting stud, and with asegment al slot to receive a stud extending laterellyfromthe carrier, and a regulating-disk journaled upon the enrrienstud, and having an eccentric slot engaging the stud of the 0peratinglever, as set forth.

2. The herein-described means for adjusting in relation to each other the rufiiing-hlade carrier and the operating-lever of a. rufing and shirring attachment for sewing-nmchines, the sameconsistingofnn eccentrically-slotted disk pivoted or jonrnitled permanently to the one of said parts, and engaging hy its eccentric slot a guide-stud projecting from the other, whereby by thrning said disk the said carrier and lever may be adjusted to and held in various positions in relation to each other, as set forth.

3. Thecomhinatioinwith the regulating-disk pivoted upon a stud projecting laterally from the rufiiing-blade carrier, and provided with an eccentric slot engaging a. stud which projects from the operating-lever, and with ecrank or handle, of the graduated cap or covering plate mounted upon the carrier-stud, adjoining-the regulating-disk, and having an opening through which the handle of said disk projects, as set forth.

In testimony that I claim the foregoing as my own I have hereto aixed my signature in presence of two Witnesses.

CHARLES GROTZ.
